WHAT IT DOES

What create_multi_output does on tdmcp — TouchDesigner MCP server

AI agents use create_multi_output to create or update resources in tdmcp — TouchDesigner MCP server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your tdmcp — TouchDesigner MCP server environment.

RISK

Why create_multi_output is rated Medium

This tool creates and modifies the TouchDesigner project structure by generating new output nodes and configurations (cropping, resizing, ending on Null operators). These changes are reversible—the created nodes can be deleted or reconfigured. While it modifies the visual system and project state, it does not execute arbitrary code, delete data permanently, or perform financial operations.

From the tool's definition The tool description explicitly states it creates outputs: 'each output is a cropped slice...ended on a Null, ready for setup_output.' The action is to 'Fan a master TOP across N projectors/displays,' which involves creating multiple new output…

RECOMMENDED RULE

The rule that runs create_multi_output safely

PolicyLayer is an MCP gateway: it sits between your AI agents and tdmcp — TouchDesigner MCP server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_multi_output, this is the rule to start with:

create_multi_output Rate-limited

create_multi_output stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
